Description

Energy-saving construction process for old building transformation
Technical Field
The invention relates to the technical field of buildings, in particular to an energy-saving construction process for old building reconstruction.
Background
Due to the long-term maintenance, the old buildings have many problems of stability, safety, usability and the like. Particularly, once an earthquake occurs, the problems of life safety and property loss which are difficult to estimate are caused to the majority of residents. Meanwhile, the cell has many years of problems to be solved urgently in various aspects such as overall planning, use functions and the like, and the specific conditions are as follows:
1. most building wall skins fall off, and some wall bodies are cracked. The waterproof layer on the roof is broken and leaks rain after being aged, and the heat insulation layer is too thin and cannot play a role in heat insulation. Particularly, the thickness of the outer wall is small, and no heat insulation layer exists, so that the cold in winter and the hot in summer are caused, and the physical and mental health of residents is seriously influenced;
2. the water, electricity and heating pipeline lines are seriously aged, so that the use is influenced and the pipelines are urgently required to be replaced;
4. the parking lot is not available, resident private cars are stored everywhere and are not managed, road blockage is caused, the cars cannot come in and go out, the resident often has contradiction corners when parking, the conglomeration is seriously influenced, and the problem of the parking lot is to be solved urgently;
5. the sports field for building the body of residents, the sports field for square dance and the sports field for body building are not available, and only children in family and wife jump;
6. there is no green land for environmental protection, and no rainwater is discharged to the underground passage, so that water is accumulated everywhere on the ground in rainy days, and sewage splashes all around when vehicles pass. Directly influences the environmental sanitation of resident's trip.
7. The building construction lacks the overall planning, and the star chess cloth that the building was built, building distance is too close, and is too little, and the dolly can not enter, and the fire engine is more difficult to pass.
The existing reconstruction technology mainly comprises the steps of digging two meters of depth and 1.5 meters of width under the vertical surface of an old building, pouring reinforced concrete to the natural ground level, and then erecting reinforced concrete columns to reach the top of the building. The disadvantages are that: the earthquake-resistant reinforcement of the old building is only carried out on the front vertical surface as the earthquake-resistant back vertical surface, so that the aim of earthquake-resistant reinforcement is difficult to achieve. This seismic resistance is a significant waste because the shock wave of an earthquake cannot determine which direction it is going from. Therefore, it is necessary to design an energy-saving construction process for old building reconstruction.
